TAC is at a 2-year low, indicating high hopes for upcoming profitability increases

Google Inc. (GOOG) finally figured out an answer of what to do with its struggling Motorola Mobility unit -- get rid of it. On Tuesday it announced it would be selling the unit for $2.91B USD to Hong Kong, China-based Lenovo Group, Ltd.'s (HKG: 0992).

I. TAC is Looking Good, Profitability is Strong

That deal overshadowed the earnings for Google, which were delivered after hours on Thursday. Overall, Google saw a substantial rise in revenue, surging from $14.42B USD in Q4 2012 to $16.86B USD in Q4 2013. That beat the expectation of analysts surveyed by Thomson Reuters I/B/E/S, who were expecting $16.75B USD.

The core internet business -- which includes the growing mobile advertising division -- earned $15.7B USD, or roughly 93 percent of the total revenue. Traffic acquisition costs (TAC) -- the fees that Google pays partners for advertising clicks -- were a strong point of the earnings reports. As a percent of revenue, these fees dropped to only 23.5 percent, their lowest level in two years indicating strengthening profitability.

Excluding the income passed on to partners, Google earned $13.6B USD, which bested the $13.4B USD that analysts surveyed byBloomberg expected.

Factoring in certain items, net income (GAAP) was at $4.10B USD ($12.01 USD/share), up roughly 15 percent YoY. That's 1.5 percent less than the $4.16B USD ($12.20 USD/share) that the Thomson Reuters I/B/E/S survey predicted, and 2.0 percent less than the $4.18B USD ($12.25 USD/share) that the Bloomberg-surveyed analysts predicted.

Along with the Dec. 2012 sale of Motorola's set-top box division to Arris (ARRS)for $2.3B USD, that move left Google baring $7.3B USD of the $12.5B USD it paid back in 2011 to acquire the American phonemaker. Motorola has $2.9B USD in cash, but Google lost $2.3B USD so far on unit. That leaves the net cost at $6.7B USD.

Overall financials are definitely headed in the right direction and should look even better in future quarters with the Motorola money-vacuum out of the picture.

But the good news for Google is that it's getting rid of the troubled unit, which saw losses growth 2.5-fold on a year-on-year (YoY) quarterly basis. Google's former headache is now Lenovo's problem to deal with.

Going on without Motorola, Google will look to continue to improve its mobile monetization and now-profitable YouTube video service. As makers of the world's most popular smartphone platform, which runs on roughly four out of every five smartphones sold globally today, Google has tremendous potential for mobile revenue.

Google is also eyeing other near product segments. It's continuing to push wearables, such as its Google Glass Explorer -- commonly referred to as "Google Glasses" -- and smartwatches. Rumors have been floating that Google may end its Nexus branded Android smartphones and tablets, but other rumors have suggested it may up the ante with a Nexus TV instead.

The Mountain View, Calif.-based software giant is also buying up a number of small robotics firms. I spoke with an executive from a firm not affiliated with Google, but familiar with the purchased firms. They told me that the overall word amongst roboticists is that Google is acting proactively and isn't quiet sure (or at least isn't indicating) where the project is headed yet.

Most of those free services may be operating at a loss on paper, but they aren't really losing. Everything Google does is directly related to raising their advertising revenue. So these services that are offered for free indirectly make Google money. The ones that are not significantly increasing ad revenue eventually get axed. Google isn't stupid enough to keep doing something that is not helping the bottom line in some way.

Well, except maybe their forays into robotics. Geeks like robots and billionaire geeks get to play with the coolest ones.
